im running a bubble magus NAC5 skimmer and it doing well in my tank rated from 80G to 135G. The price on the skimmer i couldn't say no too =)
Yea i have heard good things about these... Looking at the Nac7
ati still uses a older sicce 2500 which is a killer pump but you need the red demon pinwheel for the start up issues, the newer ati's still dont have a release date for the u.s, a vertex in180 will out perform either skimmer you listed also. a atb 840 would be the best fit and performance or the skimz sm181 kone

my tank is a 80g heavy stocked 14 fish 50+ sps 20 zoa's 6" clam and other corals and the in180 was still too much of a skimmer, honestly if ya can find a atb 840 used or even drop for a new one that would be the best skimmer for you
